Effect of ice cover roughness on local scour around bridge piers [PDF]
Scientific ReportsIn cold-region rivers, the formation of ice cover during winter markedly modifies the hydraulic conditions, leading to enhanced local scour around in-stream infrastructures such as bridge piers. To analyze the flow characteristics and maximum local scour

A Review on Recent Development of Numerical Modelling of Local Scour around Hydraulic and Marine Structures [PDF]
Journal of Marine Science and Engineering, 2022 This paper reviews the recent development of numerical modelling of local scour around hydraulic and marine structures. The numerical models for simulating local scour are classified into five categories: sediment transport rate models, two-phase models,

Local Scour Mechanism of Offshore Wind Power Pile Foundation Based on CFD-DEM
Journal of Marine Science and Engineering, 2022 The local scour around offshore pile foundations often seriously affects the normal operation of offshore wind power. The most widely used numerical simulation method in the study of local scour is the Euler two-fluid model (TFM).

Checking the Accuracy of Selected Formulae for both Clear Water and Live Bed Bridge Scour
Journal of Engineering, 2023 Due to severe scouring, many bridges failed worldwide. Therefore, the safety of the existing bridge (after contrition) mainly depends on the continuous monitoring of local scour at the substructure.

Research on the Wing-Type Antiscour Device of Pier Based on Scour Test and Numerical Simulation
Advances in Civil Engineering, 2021 In order to reduce the local scour before the antiscour device of piers, this paper proposed an improvement on a “V-type” device. That was to say, wing plates were set on the surface of the “V-type” device to enhance the diversion and reduce the local ...
